Teach Astronomy - Pseudoscience
http://www.teachastronomy.com/ A pseudoscience is something that pretends to be scientific but is not. Science follows a rigorous method which relies on the sharing of data, the basis in observations, and the fact that any scientist can assert something, but it has to be supported by evid

Constellations are drawn as stick figures connecting bright stars in the sky. This two-dimensional representation gives the impression that the stars are all at the same distance. In addition, the idea of a "bright star" can be misleading, as the apparent brightness we see depends upon bot
